“The two big blocks labeled 1 and 2 are definitely loose - don't use them! The one labeled 3 may also have been loose; I can't be certain. I bailed pretty quickly once they started shifting around. FWIW, I was standing to the left of them near the white rock that's covered in crap. I was basically bear-hugging the stack and heel hooking my way up onto it with my right foot on a little ledge toward the bottom of the three when the whole thing pivoted a bit. Then I freaked out and came down.”
